Alright. First off, lets see the account that posted the picture on Minecraft Wiki.

<--You can see that is was posted by the user "4td0"
Well, let's take a look at the user page on Minecraft Wiki. www.minecraftwiki.net/wiki/User:4td0
Take a look at what one of his contacts are listed as:
"Funnyjunk - genericnickname"
There is proof.
"But hey, ANYONE could have edited that page!"
Well, you would be right. Let's take a look at the Youtube page, where no one else can edit it. www.youtube.com/user/The4td0
Take a look to the right of the channel.

"Want to contact me elsewhere?
Here is where I tend to roam:"

Followed by links.
One of them to funnyjunk
